^Windows 7 introduces a Content view which shows details as well as thumbnails

Twin-panel file managers have obligatory connected panels where action in one panel results in reaction in the second. Konqueror supports multiple panels divided horizontally, vertically or both, but these panels do not act as twin panels by default (the user has to mark the panels he wants to act as twin-panels).

Information on what networking protocols the file managers support. Note that many of these protocols might be supported, in part or in whole, by software layers below the file manager, rather than by the file manager itself; for example, the Mac OS X Finder doesn't implement those protocols, and the Windows Explorer doesn't implement most of them, they just make ordinary file system calls to access remote files, and Konqueror either uses ordinary file system calls or KIO slave calls to access remote files. Some functions, such as browsing for servers or shares, might be implemented in the file manager even if most functions are implemented below the file manager.

^NFS support requires either the freely downloadable Windows Services for UNIX or is built-in starting with Windows Vista Enterprise and Ultimate editions as Subsystem for Unix-based applications (SUA).

Information on what file searching features the file managers support. RegExp include the possibilities of nested Boolean searches, thus implicitly all file managers supporting RegExp search support also Boolean searches.

^The exact history is unknown. This date comes from changelog entries in the src/TODO file in the Git repository (SHA1: eb6b3842a). But it is probably earlier than that. Dec 1997 was release v4.1 already.

^ abDirectory Opus 5.82 Magellan II is the last commercial version available for Amiga. Full and registered version has been released for free with the AmiKit distribution. Directory Opus 4 is maintained separately under an open source license.

^The text interface, which can be partially graphical with some plugins, such as embedded image/video viewers, for example. But the text interface is only emulated with the ConEmu mod - it is graphical and TrueColor in reality.

^Mass Rename is a feature to rename large number of files in a convenient way and including a preview, see the screenshot for an example. Common options are subdirectory inclusion, wildcards, manual mode (offering to edit names as text files in editors), counters, time related fields (e.g. "date created"), path related fields (e.g. "parent directory name"), regular expressions etc.

^Altap Salamander offers to show only selected files and hide unselected ones, also in picture viewer etc. For selection, the usual wildcards and add/subtract/intersect with 1...N stored selections are offered.

^ACL is dependent on the type and version of file- and operating system. Altap Salamander offers quick access to owner, auditing and permission settings in WinXP with NTFS 5.

^Save searches: Ability to save templates containing all search settings (file filter, metadata requirements etc.). Results of saves searches are always live, so not the results but the search conditions are saved.

^Also known as iterative searches. For example the ability to finish one search and then perform a new search a) only within these results (intersect the two result sets / the requirements of both searches have to be met), 2) adding to these results (combine both result sets to a bigger set) or 3) subtract from those results (original result set reduced by intersection of result sets).
